Its ENERGY STAR score went from 99 in 2021 to 82 in 2022 (-17 points); its best year on file was 2021, at 99. Site EUI moved from 49.0 kBtu/ft² (2021) to 62.8 kBtu/ft² (2022), an 28% increase. Reported emissions went from 338 tCO₂e to 479 tCO₂e over the same span (up 42%).
What does an ENERGY STAR score of 82 mean?
ENERGY STAR scores run from 1 to 100 and are computed by the EPA's Portfolio Manager as a percentile against similar buildings nationwide, adjusted for climate, size and use: a score of 82 means the building performs better than about 82% of its national peers. BuildingCensus bands the score into report-card grades; 82 falls in band B — above median (70–84). Scores of 75 or higher meet the threshold for ENERGY STAR certification; certification itself is a separate, verified application that the disclosure does not record. In Denver, 54% of scored buildings are at 75 or above.
Site energy-use intensity (EUI) is the energy a building uses on site in a year divided by its floor area, in thousand Btu per square foot — lower is more efficient. Mount Loretto's 62.8 kBtu/ft² across 87,588 sq ft works out to about 5.5 billion Btu (1,612 MWh-equivalent) in 2022. The disclosure also reports 547,700 kWh of electricity and 36,337 therms of natural gas for the year.
